EDS/WDS mapping: a review of X-ray techniques

Spectral imaging collects a full energy spectrum at each pixel in your image. Faster acquisition times and increased automation have made it one of the more commonly used microanalytical methods in SEM. We use a lunar meteorite to review the many mapping methods that spectral imaging data provides. Our review includes elemental mapping, semi-quantitative elemental mapping, quantitative elemental mapping, and phase mapping with COMPASS software. We explore benefits of each, and offer tips on choosing the right method for your application.
